One of the problems at the root of the poor management of forest resources in Cameroon is the lack of good governance. This study aims to evaluate the governance put in place by the government of Cameroon to ensure better management of Prunus africana. It takes a critical look at the three pillars of forest governance in relation to the management of the resource, which are: policy, legal, institutional and regulatory frameworks (1);planning and decision-making process (2);and finally the implementation, enforcement and compliance of regulations (3). The assessment was conducted using the guide recommended by FAO-PROFOR. Individual and focus group interviews were conducted with stakeholders involved in the P. africana management process. The results in the form of assessment scores revealed poor governance in the management of the resource. This is due to non-compliance with Pillars 2 and 3 on the planning and decision-making process as well as the implementation and enforcement of regulations through weaknesses in the principles of transparency, accountability, the effectiveness of management measures and stakeholder participation. These are the points on which management strategies should be based for better management of P. africana in the production forests of the Adamawa region.

利用形状记忆合金(shape memory alloy,SMA)丝超弹性和激励回复产生较大驱动力的特性,将不同预拉长度及根数的Ni-Ti SMA丝预埋入混凝土模型梁中,研究了混凝土梁加载过程中Ni-Ti SMA丝电阻变化率与混凝土梁裂缝宽度的关系以及Ni-Ti SMA通电激励过程中混凝土梁裂缝恢复的变化规律.试验中考虑了SMA滑移的影响,并通过理论计算对其进行验证,计算时考虑了锚具造成的附加电阻的影响.结果表明:SMA显著提高了混凝土梁的变形能力和抗裂能力;在通电激励后,混凝土梁在Ni-Ti SMA激励回复效应驱动下,挠度迅速恢复,裂缝闭合;增加Ni-TiSMA总截面面积可提高合金对混凝土梁的驱动效果;在裂缝宽度小于1.5 mm时,Ni-Ti SMA电阻变化率和混凝土梁的裂缝宽度呈明显的线性关系;钢筋塑性变形的存在,对混凝土模型梁的变形回复起阻碍作用.

Polyphenolic compounds with relatively high antioxidant activity obtained from subcritical water extraction of apple pomace were assessed for encapsulation by spray drying technique, making use of polymeric substances co-extracted with the polyphenolic compounds. Comparative assessments were carried out of the directly encapsulated subcritical water extract (SWE) products with particles formed when encapsulated with the addition of hydroxyl propyl-β-Cyclodextrin (SWE + HPβ-CD). The powders were characterized for their physico-chemical properties such as, moisture content, density, particle size, hygroscopicity to assess their suitability within cosmetic formulations. The SWE and SWE + HPβ-CD encapsulated products resulted in different physical properties. Although the particle size was less than 4 μm for both products, the direct encapsulation (SWE) was highly hygroscopic and this property was significantly reduced with addition of HPβ-Cyclodextrin (SWE + HPβ-CD). Scanning electron microscopy (SEM) and Fourier Transform Infrared (FT-IR) spectroscopic were em-ployed to analyse the micronised powders to support evidence of encapsulation. Both techniques revealed the interaction between compounds in extract and the carrier HPβ-Cyclodextrin suggesting successful encapsulation. The effect of storage conditions on retention of antioxidant activity of the subcritical water extract was evaluated within 35 days for extracts with and without the carrier HPβ-Cyclodextrin. Hydroxyl propyl-β-Cyclodextrin offered protection against degradation of antioxidant compounds thereby potentially extending the shelf-life and making the encapsulated powder suitable for incorporation in cosmetic and pharmaceutical applications.
